The GPIB (general purpose interface bus) was specifically designed to connect computers, peripherals and laboratory instruments so that data and control information could pass between them.
It is also known as IEEE-488 or HPIB, and is electrically equivalent to IEC-625 bus. It is defined completely in the IEEE standard 488.1-1987 Standard Digital Interface for Programmable Instrumentation.
